Iingxaki ze eyestrain okanye ipresbyopia Zibonakala ikakhulu kwiipesenti ezingama-90 zamadoda ukusukela kwiminyaka engama-45. Le yimeko eqhelekileyo yokwaluphala kwaye yongeza nakweziphi na iimpembelelo umntu anazo. Nokuba ujonge kude, myopia, okanye astigmatism, amadoda akule minyaka aqala ukuba neengxaki zombono.
Okulandelayo, siza kukuxelela yonke into enxulumene nale ngxaki yombono, sikunceda ukuba uqaphele iimpawu zayo kwaye ubone zonke izisombululo ezinokubakho. Ngaba uyafuna ukufunda konke ngayo?
I-Presbyopia kunye neziphumo zayo
Yimeko yamehlo eqhelekileyo enxulumene nobudala. Ixesha elininzi nangaphezulu lichithwa phambi kwezikrini kwaye sihluza amehlo ethu ukubona kude okanye kufutshane nezinto.
Kule minyaka idlulileyo, ukubona "amavili" kunye noko sikubiza ngokuba yi-presbyopia kuyavela. Le ngxaki yenzeka ngalo mzuzu xa ilensi yendalo, ebizwa i-crystalline, iqala ukungabi bhetyebhetye kwaye iqine. Oku kubangela ukuba iingxaki zitshintshe ubume kunye nemizamo yokubona kwaye zikhokelela ekusebenzeni kakubi kwezihlunu ezibangqongileyo. Xa oku kusenzeka, indawo yokuhlala ilahlekile apho ilensi ifuna ukwanda ukuze ijonge kufutshane.
Ke ngoko, sifumana ingxaki phantse kuma-90% yamadoda ngaphezulu kweminyaka engama-45 ukugxila kufutshane. Ezona mpawu zixhaphakileyo ukufumanisa i-presbyopia zezi:
- Ukudinwa okubonakalayo Kwenzeka ikakhulu kwiindawo ezinokukhanya okungalunganga.
- Kunzima ukugxila kwizinto ezikufutshane. Xa sifuna ukufunda ileta okanye ukubona into kufutshane, kodwa asikwazi ukuyigxila kakuhle kwaye sibona ukufiphala.
- Intloko ebuhlungu. Ukugqithisa okufunekayo ekugxininiseni indawo yokuhlala kubangela iintlungu zokuphelelwa ngumzimba.
- Ukulibaziseka ekugxilwe ixesha elide. Kwenzeka xa sijonga into ekufutshane okwexeshana kwaye kusithatha ixesha elide ukuphinda siqwalasele into ekude.
Umqondiso ocacileyo wabo bonke abo banengxaki kule ngxaki kufuneka bayise kude le nto ifundwayo ukuze bajolise kuyo.
Kufunyaniswa njani kwaye luyintoni unyango lwayo?
I-Presbyopia kufuneka inyangwe usebenzisa iiglasi, Ngaphandle koko, imisebenzi yemihla ngemihla iba nzima kakhulu. Ukufunda iphephandaba elilula kusasa kunokuba yingxaki enkulu ukuba une-eyestrain. Kwiminyaka engama-45 ubudala ubunobomi obunemveliso kwaye kuyingxaki enkulu ukuba nazo zonke ezi mpawu zingasentla. Ukongeza, oku kukwabangela ukwanda kweengxaki ezinje nge-blepharitis kunye nokukhula kwamehlo.
Ukuxilongwa kwenziwa ngovavanyo oluqhelekileyo lombono. Imeko yombono iqikelelwa kufutshane nakude. I-ophthalmologist inokuba noxanduva lokulawula nayiphi na enye indlela ngezifo kuvavanyo olupheleleyo lweliso lakho.
Ukuqala unyango olwaneleyo, kuya kufuneka sigxile kuhlobo lwesigulana, iminyaka esiqale ngayo ukubandezeleka kunye nemisebenzi yemihla ngemihla. Inkalo ebaluleke kakhulu ekufuneka ithathelwe ingqalelo kukuba ingaba isigulana sinesiphene esitsalayo.
Kukho iiglasi zokuzikhulisa kwabo bafuna ukufunda okuthile, kodwa ayisiyonyango okanye indlela yokunyanga. Unyango lunenjongo yoku bonelela ngombono ogqibeleleyo ukuya kuthi ga kwi-33 cm kude. Bonke abo banengxaki yokubona nge-diopter ukusuka ku-1 ukuya ku-3 banokuyifumana.
Ukuba ufuna ukufumana ulungiso olubonakalayo olusondeleyo nolukude kwiilensi ezifanayo, kuya kufuneka wenze amayeza awodwa. Ihlala yahlukile kwiso ngalinye. I-Presbyopia iqhubela phambili kwaye unyaka nonyaka ukuya kwisiqingatha seminyaka emithathu isixa sokongezwa esongezwe kwinxalenye esezantsi yeenguqu zelensi ukuze amayeza atshintshe.
Iiglasi ezigqwesileyo zolu hlobo lweengxaki ezibonakalayo zezi ziqhubela phambili. Nangona ekuqaleni sidinga ixesha lokuziqhelanisa, kamva zezona ziqinisekisa umbono ongcono kokubini kufutshane nakude nakumgama ophakathi.
Yahluke njani i-presbyopia kunye ne-hyperopia?
Ngamanye amaxesha siyazibhida ezi ngcamango zimbini. Inkqubo ye- Iimpawu ze-presbyopia kunye ne-hyperopia Ziyafana kodwa azifani. Dideka ngu ube kufutshane neengxaki ekugxilwe kuzo.
Umahluko ogqame phakathi kwezi ziphene ezibonakalayo usemvelaphi. Unobangela wokuguquguquka kwelensi evelisa i-presbyopia yenzeka kubantu abaneminyaka engama-45 ubudala okanye ngaphezulu. Nangona kunjalo, i-hyperopia ngenxa yemfuza yemfuza yamehlo. Kwenzeka xa ubungakanani beliso buncinci kunesiqhelo. Ihlala ibonakala ebantwaneni nakubantu abancinci.
Kwi-presbyopia, iilensi ziphulukana nobuchule bayo bokuziqhelanisa nokuhamba kweminyaka kwaye i-elasticity ayikuvumeli ukulungiselela iindlela.
Nangona zombini zichaphazela umgama omfutshane, i-hyperopia kwizidanga eziphezulu inokukhokelela kukungaqhelekanga kombono kumgama ophakathi kunye nomgama omde. I-Presbyopia inxulunyaniswa ngokupheleleyo nobudala. Iimpawu ziqala ukubonwa kwiminyaka engama-40-45 ubudala
IZiko eliPhezulu leOcular
Iziko leMfundo ePhakamileyo isebenza kunye neelensi eziqhubela phambili eziza kukunceda ukusombulula ezona mpawu zaziwayo zokubona udiniweyo. Ukuze unxibelelane nabo, kuya kufuneka ubhalise kwiwebhusayithi yabo kwaye baya kunxibelelana nawe. Nje ukuba uthethe, bacwangcisa uvavanyo lwamehlo ukuvavanya imeko yakho.

Kuxhomekeka kwisifo, bayakuchaza ngakumbi unyango olusekwe ekusebenziseni iiglasi eziqhubayo ezilungiselelwe wena. Kwiintsuku ezimbalwa ungazithatha kwaye ulibale malunga nefuthe le-presbyopia.
Kukho iinkampani ezininzi ezijongene nonyango olubonakalayo olunikezela ukulungiswa kunye nonyango lwamehlo adiniweyo. Inketho enomdla inokuba yi-Instituto Superior Ocular ngenxa yayo xabiso. Nangona umbono ungumba obaluleke kakhulu kubomi bethu, kufuneka sihlale kwibhajethi. Amaxabiso eli ziko asezantsi kuba iilensi zawo zivela ngqo kwiilebhu zazo.
Kwelinye icala, kubalulekile ukuba kwenziwe isicwangciso sonyango esintsonkothileyo nesenzelwe wena. Oku kunokukunceda wenze izinto ezintsha kwaye unike izisombululo ezitsha.
Ngoku ukuba uyazi iziphumo, oonobangela, kunye neziphumo ze-presbyopia, lixesha lokuba ujonge ukubona kwamehlo. Khumbula ukuba xa uyinyanga ngokukhawuleza, awuyi kuba nangxaki kwixesha elizayo
